## Detailed Description

Thin iconv() wrapper.

glibmm provides Glib::convert() and Glib::locale_to_utf8() which are likely more convenient than the raw iconv wrappers. However, creating an IConv object once and using the convert() method could be useful when converting multiple times between the same charsets.

## Constructor & Destructor Documentation

Glib::IConv::IConv | ( | const std::string & | to_codeset,
|  | const std::string & | from_codeset
| ) |  |

Open new conversion descriptor.

Parameters:

  to_codeset | Destination codeset.
  from_codeset | Source codeset.

Exceptions:

  Glib::ConvertError |

Glib::IConv::IConv | ( | GIConv | gobject | ) | `[explicit]`

Glib::IConv::~IConv | ( |  | ) |

Close conversion descriptor.

## Member Function Documentation

std::string Glib::IConv::convert | ( | const std::string & | str | ) |

Convert from one encoding to another.

Parameters:

  str | The string to convert.

Returns:
  The converted string.

Exceptions:

  Glib::ConvertError |

GIConv Glib::IConv::gobj | ( |  | ) | `[inline]`

size_t Glib::IConv::iconv | ( | char ** | inbuf,
|  | gsize * | inbytes_left,
|  | char ** | outbuf,
|  | gsize * | outbytes_left
| ) |  |

Same as the standard UNIX routine iconv(), but may be implemented via libiconv on UNIX flavors that lack a native implementation.

glibmm provides Glib::convert() and Glib::locale_to_utf8() which are likely more convenient than the raw iconv wrappers.

Parameters:

  inbuf | Bytes to convert.
  inbytes_left | In/out parameter, bytes remaining to convert in inbuf.
  outbuf | Converted output bytes.
  outbytes_left | In/out parameter, bytes available to fill in outbuf.

Returns:
  Count of non-reversible conversions, or `static_cast<size_t>(-1)` on error.

void Glib::IConv::reset | ( |  | ) |

Reset conversion descriptor to initial state.

Same as `iconv(0, 0, 0, 0)`, but implemented slightly differently in order to work on Sun Solaris <= 7. It's also more obvious so you're encouraged to use it.
